The trick is to look at the line immediately following the first warning:

[  168.609273] WARNING: at lib/debugobjects.c:260 debug_print_object+0x8e/0xb0()
[  168.609277] ODEBUG: activate active (active state 1) object type: rcu_head hint:           (null)

This happens when someone invokes kfree_rcu() or call_rcu() on an object
that had already been either kfree_rcu()ed or call_rcu()ed and whose
grace period has not yet ended.

So let's look at the stack trace:

[  168.609371] Call Trace:

It appears that ipc_rcu_putref() is the culprit, maybe with the help
of the semtimedop() system call.  The remaining warnings are due to
RCU's lists getting tangled.

The output would probably be less confusing if RCU simply leaked callbacks
that the debug-objects facility complained about.  This would not be
perfect, but better a memory leak or even an hang than memory corruption.
Though of course even memory corruption preceded by warnings is better
than silent memory corruption.

I will take a look at that.
